The 135-degree split point eliminates bit walking at the start of a hole, producing accurate, clean entries without center-punching in many applications. The black oxide finish adds a layer of corrosion resistance and helps reduce friction during drilling. A reinforced core geometry resists bit breakage under load, extending service life in demanding jobsite conditions. This bit is suited for everyday trade use by electricians, plumbers, HVAC technicians, and general contractors who need a dependable, cost-effective drilling solution.\u003c\/p\u003e\u003cp\u003eThe QJDIB-DB-028 handles a broad range of common materials encountered in trade work, including angle iron, wood framing, and PVC pipe or conduit. Its 1\/4-inch diameter makes it a standard choice for pilot holes, fastener clearance holes, and conduit knockouts in light steel. The bit performs well in both handheld drill drivers and bench-mounted drill presses, making it a versatile addition to any service van or tool kit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point prevents walking and improves hole-start accuracy\u003c\/li\u003e\n\u003cli\u003ePrecision-ground high-speed steel construction for consistent cutting performance\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides corrosion resistance and reduces drilling friction\u003c\/li\u003e\n\u003cli\u003eReinforced core resists breakage under lateral and axial load\u003c\/li\u003e\n\u003cli\u003eSuitable for angle iron, wood, and PVC applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or stock drill bit compatible with standard 3-jaw chuck drill drivers and drill presses accepting 1\/4-inch shank bits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLicensed electricians, plumbers, and HVAC technicians typically install or use this bit during rough-in and service work. Ensure the chuck is fully tightened and the workpiece is secured before drilling. Use appropriate personal protective equipment including eye protection when drilling metal or PVC.
